Automatic Latest Content Not Working

I have an automatic newsletter set up to send excerpts of two of my latest blog posts following by a list of 5 more recent content links. It worked for a few days, then it stopped. Only 1 of the recent excerpts shows up and none of the 5 recent content links show. I checked the settings and they are still the same, but it’s not working properly.
